Tacky foods 😀😀😀😀😀

Some food material that have been dehydrated exhibits thermoplasticity (the property of softening upon heating). A cellular food (plant and animal tissue) has structure and some rigidity, fruit or vegetables juices do not and are high in sugars and such that soften and melt at drying temperature. For example, if sugar syrup is dried in a pan, when the water is removed, the solids will be in a thermoplastic tacky condition that stick to the pan and are difficult to remove and with cooling, harden into a crystalline glass form........................................

problem of plant living in fresh water habitat

Buoyancy The density of fresh water is considerably less than that of the sea and such floatation is a greater problem for fresh water plankton. There is occasional flooding which submerges the plants. The water lilies, water lettuce, water hyacinth are able to stay afloat because of the air spaces in the lower part of the leaves as well as in the skins and roots.

Processing of animal products

Alot of products are derived from livestock, both edible and inedible, for this discourse, we look at the edible products. The edible products include, milk, meat eggs. Milk processing Milk is the lacteal secretion from the mammary gland of females livestock. Although in modern days, milk can also be gotten from plants eg soybean milk, coconut milk. The milk from animals from cow, goat, buffallo etc. The milk is a very good vehicle for transmission of pathogens so milk handlers should exercise the utmost level of personal hygiene, the milk processing area should be sanitized. The milk handlers must be free from gastro-intestinal infections, no coughing, sneezing, diarrhoea etc. Note that the dairy animals are kept in hygienic condition, sick or animals receiving treatment should not be milk. The udders should be washed prior to milking in order to reduce the risk of contamination of the milk. Once milk is collected from the animals through a milking machine, the t...

The Nucleic Acids

These are molecules that are essential to and characteristic of life on earth. They form the genetic material of all living organisms including the simplest virus. These compunds are found mainly in the nucleus. They are DNA (Deoxyribonucleic acid) and RNA (Ribonucleic acid). Nucleic acids have the same basic structure in all organisms.
